Look up online "2011 Hyundai Sonata wandering" and you'll
understand why the concern. Although most of the issues
were resolved by the third model year of the YF body Sonata,
it is still good to havr alignment checked, especially on a
used one with 30,000 miles.

Another contributor to the wandering was the electric power
steering and what mode it was set in at the factory. Mine was
set to 'Soft'(maximum boost, minimum driver effort). I had my
dealer set it to 'Sport'(minimum boost, most driver effort needed
to steer car). In soft, even slight changes to the road angle, or
a mild cross wind, would wrest the wheel from drivers' hands!
It was reminiscent of the 70s 'one fingered' steering on
full size models.


Sport mode was a huge step in normalizing the handling/road
feel of my Sonata, but I figured finding a way to maximize
caster - within specs - would really ice the cake.
